Blue Whisper: The Fascinating World Beneath the Waves
Blue Whisper dives beneath the waves to explore the little-understood world of underwater communication. The film investigates how marine creatures signal, sense, and speak to one another across the ocean's depths, a field science is only beginning to map. Its immersive 4K footage brings the hidden sounds and behaviours of the sea to life. Beautiful and revealing, it opens a window on an ocean full of quiet conversation.
